Translation - Voltage Levels
Texas Instruments
This dual-bit noninverting bus transceiver( SN74LVC2T45DCURG4 ) uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCAaccepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCBaccepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
